Ok so first I'd like to say my main breaker/service disconnect is on a pole 100ft away from my house. 200amps.
I had installed a 125 amp subpanel next to my 200 amp main distribution panel in preparation for my pv system. Using a 125 amp breaker providing power to the sub located inside of the main. After more research and a thread on this forum I'm realizing that the power from my pv system would ultimately land on the bus bars of the main which would violate the 120% rules.
Does anyone see a problem if I were to remove the 125 amp breaker from the main panel, extend those wires to do a tap b4 the main 200amp breaker inside of my main panel to feed the subpanel. I would then need to install the 125 amp breaker in the backfeed slot of my subpanel, remove the load wires from the lugs inside of said panel, and connect them to the 125amp breaker providing over current protection for the feeder wires. In my peanut sized mind this would bypass my main so the 120 rule would only apply to the subpanel. I need 2x 40amp double pole breakers but I would opt for the 3rd option which tosses out the 120% rule and I'd be required to put a safety sticker on the subpanel stating that the combined ampacity of the breakers (excluding the supply) can't exceed the ampacity of the busbar.
Thoughts opinions?
I had considered doing 2 taps and adding 2x fused disconnects but this would be consideredably more work and I don't see how this method would protect the feeder circuit any differently than the tap to 125 amp breaker. Also I'm fairly confident in the legality of using the 3rd option.
Basically this circuit is already wired up so were not talking about hypotheticals, I already have safety safety switches installed ect. I'm thinking I could possibly use like a fusible air conditioning disconnect in between the tap and the safety switches if I absolutely had to abandon the subpanel all together. It just stinks bc I got this subpanel inspected already and idk if my inspector would notice if I messed with it. Probably not but he might.
I installed this subpanel over last winter and it never even occurred to me that It still wouldnt help me in the current configuration. I guess I shouldn't be surprised, I've basically done everything in this setup twice already, some things 3x...
